An experiment was conducted in which the heat transfer from a sphere in sodium was measured. The sphere, 0.5 in. in diameter, was pulled through a large sodium bath at a given velocity while an electrical heater inside the sphere maintained the temperature at a set point. The following table gives the results of the experiment. Determine how well the above data are predicted by the appropriate correlation given in the text. Express your results in terms of the percent difference between the experimentally determined Nusselt number and that calculated from the equation.
